I just picked up the CZAR (82) if u get dumped on like whistler I would go with it.  Handles pretty much anything, plus you won't be giving anything up on a pow day, has 62cm early rise.  Surprisingly skis hardpack fairly well, due to traditional camber, although slight, over most of the ski.  Work at a shop, got to demo new stuff last year, on a bulletproof day : (  If you ski hard you should be able to handle the 82 fairly well,  but a 74 wouldn't be bad either.  Didn't ski the Lord, so I don't know.  Remeber, in an All Mountain ski WIDER IS BETTER.  Let me know what you decide.
